The Thunder (57-21) continued their push to claim the top overall seed in the Western Conference, while the Jazz lost some momentum in their battle with the Los Angeles Lakers for the final playoff spot.

Utah (41-38) entered with a half-game lead and the tiebreaker over the Lakers, who faced New Orleans in a late game Tuesday.

Al Jefferson’s three-point play pulled Utah within 84-78 with 55 seconds left and Paul Millsap’s dunk made it a four-point game, but Durant hit two free throws and Westbrook stole the inbound pass to seal it for the Thunder.

Serge Ibaka helped Oklahoma City build a big lead with 10 points, four rebounds and three blocks in the third quarter.
